Quality Control

Our production of 4,8-Diamino-1,5-dihydroxy-2-(4-methoxyphenyl)anthraquinone adheres to a stringent quality management system. Every batch undergoes rigorous analytical testing to ensure identity, purity, and consistency meet exacting customer specifications. A comprehensive Certificate of Analysis (COA) detailing purity (typically by HPLC), physical characteristics, and impurity profiles is provided with each shipment to ensure full traceability and compliance with your quality protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its light-sensitive and easily oxidized nature, it is recommended to store this material under an inert atmosphere (e.g., nitrogen or argon) for long-term stability. Keep away from strong oxidizing agents.
